Industry watchers have repeatedly said that BlackBerry’s efforts to bring BBM to Android and iOS are far too little, too late to matter now that a handful of behemoths dominate the space. While that may or may not be true, we know beyond a shadow of a doubt that there is definitely a healthy amount of buzz surrounding the imminent release of BlackBerry’s famous messaging service on Google and Apple’s mobile platforms. And now, we have some potential good news for those eager to try out the new app — according to a new report, BBM will launch for both Android and iOS later this week.

UPDATE: It looks like this report was close, but off by one day — or plans changed at the last minute. BlackBerry announced in a “breaking” blog post on Wednesday that BBM for Android will launch at 7:00 a.m. EDT on Saturday, September 21st.
